Definitions
- the invention relates to a wheel theft protection according to the preamble of claim 1.
- a wheel theft protection is off GB-A-2 006 371.
- wheel locks also called wheel locks, used.
- wheel locks instead of the normal, unencrypted Wheel bolts or nuts as they are typically from Vehicle manufacturers are installed, special wheel bolts or Wheel nuts used with a drive range that is not standard Keys to capture is possible and also with common tools, such as for example, pliers, pipe sections, internal gear drive parts, etc. can not be solved.
- Such secured wheel bolts or wheel nuts are collectively referred to as fasteners.
- the fastening part is assigned a key that is plugged in the axial direction.
- the drive and the guide area work together with the key.
- the key has corresponding areas, namely a drive part and a guide part. Both are complementary to the respective areas executed the fastening part.
- the drive part forms in the direction of rotation enough stop surface, so the required torques can be transmitted.
- the recesses in the drive area are after arranged an encryption, so that only the actually appropriate Key that has the same complementary arrangement with the Fastening part can interact.
- the guide area serves the axially opposite the attached key to guide and hold the fastening part. Without a management area would then, if a sufficiently large torque is applied, e.g. the nominal torque, the key is inclined to the axis of the fastening part make, this is a screwing or loosening the screw of the fastening part almost impossible.
- the management area must therefore be sized so that it is sufficiently strong to transversely to Axis of the fastening part attacking tilting forces, as in the normal Bolting processes consciously occur to be able to intercept.
- the invention has set itself the task of safety of the fastening part of the aforementioned type to further improve, while also weight to save.
- the invention thus proposes that the recesses, in particular as Keyed holes are executed, are lower than the outward adjoining edge area.
- this increase is to the outside and above the edge area already at a distance from the axis present, in which the recesses are located. For example, this starts the rise of the edge area in the middle of the keyholes. The rise is outward, beyond the area of the keyholes advantageously continuing.
- the increase is preferably monotonous.
- This edge region according to the invention also helps with the preparation of the key, he facilitates the slipping of the projections (pins) into the keyholes.
- the edge region increases at an angle beta between 5 ° and 75 ° relative to a radial plane. Particularly this angle beta is in the range of 20 ° to 60 °. These angular ranges have proven to be cheap. Because the border area is already inside the keyholes increase, the following is achieved: Screws, so turning around the axis, hit the pins of a key to the inner wall of the keyholes. This contact is ever according to the shape of the pins at a certain angle. For round pins contacted the mantle line of the pen, on the circle around the axis and through the Pin axes, the associated keyholes in an axial plane, Torque is transmitted optimally.
- the intended for the fastening part key has a preferably one Chamfer, which preferably complementary to the slope of the edge region is and with the key in contact with the edge area comes.
- This chamfer preferably runs at the same angle and also has the same gradient as the border area.
- the edge region is preferably rotationally symmetrical, thereby simplified itself the production of the fastening part. But it is also possible in to incorporate the edge area tracks, each from a keyhole go out and run outwards in a spiral, preferably in the direction of release.
- the guide region is at least at one point with a sun formed small sized cross-sectional area that the rated torque, as necessary for screwing and loosening the screw connection are not alone about the guide head can be initiated, it rather comes to a shearing or destroying.
- This is especially true reduces the diameter and / or the wall thickness of the guide member. This may be over the entire length of the guidance area or only over a part of this total length. In any case, weight is saved.
- the guide area is now mechanically so strong that he at Use of a suitable key sufficient guidance against Tilting and centering of the rotary motion offers.
- an incision is made extending between the guide head and located in the drive area. Located at the lowest point of this incision the small measured cross-sectional area. It will be a breaking point created. The management area will be aware of the place locally The incision has weakened so much that it shears in the area of the incision, when a torque between the guide head and the drive area or the bolting area attacks.
- the management area has a Recess and the wall thickness of the guide area is low, in particular formed under 3 mm.
- This training is also suitable for Wheel nuts.
- the recess can be made so large that a threaded bolt can protrude through the guide area.
- Nominal torque is understood to mean the torque that follows Regulation of the car manufacturer for tightening the screw connections is provided. Typical nominal torques are for example 170 Nm.
- the guide head is preferably rotationally symmetrical, in particular a Turned part, thereby he can when putting the key on the mounting area secure the axial assignment.
- the key can thus be relative be turned to the fastening part until it is positively in the recesses intervenes. Accordingly, the key also has a guide head corresponding centering area, which is called the guide part.
- the drive area projections can be provided in this Case then has the key the corresponding complementary recesses or returns.
- the management area either protrude in the axial direction positive from the drive range and has the key as a guide part a corresponding receiving bore for the guide area, or is the guide area as a central blind hole trained and it jumps on the key positive a lead, which then has the small measured cross-sectional area or made ineffective becomes.
- the Contact surface to which an axially attached key comes to rest, in an angle less than 90 °, preferably less than 70 ° to the axis.
- the contact surface then runs on a cone and is designed so that when missing Guide area tilting the key relative to the fastening part is possible. So it's the guide area that has the axial assignment between key and mounting part secures. If he does not exist, should an equiaxed, joint turning of key and fastening part not possible. This is especially due to an oblique or even arcuate, outwardly convex contact surface reached.
- the predetermined breaking point is in the immediate Near the drive area. This leaves you, if you only via the guide head wants to unscrew the attachment part and this shears according to the invention, the smallest possible remainder of the guide area back on the attachment part.
- each projection and / or the recess in the circumferential direction with an oblique Surface provided.
- a release causes a sliding of the key on these inclined surfaces and at the same time an axial lifting of the key, if the key is not for each return of the fastening part an associated projection or Driver has.
- a protective cap is provided, which is attached to the management area. She is small in size Cross-section surface engaged.
- This protective cap is preferably designed that with attached protective cap, the fastening part as a conventional wheel nut or wheel bolt looks like. The returns are then covered.
- the key of Figure 1 has a guide member 20, which with a Guide portion 22 of the fastening part of Figure 2 cooperates and the concentric with an axis 24 extends. He still has a drive part 30, which has distributed according to an encrypted arrangement pins 32, the Form protrusions. They run axially, there are a total of four projections provided, of which two in Figure 1 and three in Figure 3 can be seen.
- the driving part 30 of the key is complementary to a driving area 34 of the fastening part of Figure 2, which is designed here as a wheel bolt is.
- the key has a polygonal part 40, the two graded arranged and oriented in the direction of the axis 24 hexagonal, Reference is made to DE 296 17 043 U.
- the guide member 20 by a blind bore realized in the bell-shaped housing of the key, this hole is concentric with the axis 24 and open at the bottom.
- the guide part 20 is in its axial depth and its inner dimension the guide area 22nd customized.
- the guide portion 22 is concentric with the axis 24 and extends in the opposite direction to a threaded portion 42, which is also concentric to the axis 24 is. He is in the embodiment shown as external thread executed. He is a corresponding mating thread (not adjusted) hub adapted.
- the guide area ends in a guide head 26, here the shape of a flat cylinder has. He is the blind hole, the guide part 20th forms, adapted.
- a guide head 26 here the shape of a flat cylinder has. He is the blind hole, the guide part 20th forms, adapted.
- the guide portion 22 tapers clearly, it consists in this section of a truncated cone.
- the diameter decreases towards a small sized cross-sectional area 28, Also called breaking point, where it is slightly less than 40% of Diameter of the guide head 26.
- This cross-sectional area 28 is located directly adjacent to the drive region 34.
- the predetermined breaking point 28 is dimensioned such that one alone on the guide head 26th acting rated torque (with the drive area 34 or clamped threaded portion 42) to a shearing of the guide area 22 leads.
- the nominal torque is understood as the torque that the automaker prescribes for the concrete fastening part.
- typical Nominal torques are 170 Nm.
- the cross-sectional area 28 can be configured as desired. Furthermore, the illustrated cone shape only an example. It is also possible that the whole Guide portion 22 has the cross-sectional area 28, so e.g. cylindrical is. But preferred is a specific point at which take place a predetermined breaking can. This location should be as close as possible to the drive area 34, so that as little as possible remains from the guide area 22 during shearing and thus as little as possible attack options for a release tool Offer.
- the fastening part according to FIG. 2 can be regarded as a normal screw, the threaded portion 42 forms the screw shaft, the drive region 34 forms the head and the guide portion 22 is axially upside down placed.
- the drive region 34 comes only with the drive part 30 in Contact, when guide member 20 and guide portion 22 already engaged are.
- the drive region 34 has a contact surface 36 which is oblique to the axis 24 runs. It lies on a cone whose tip is above the attachment part, So above the guide area 22, and is the one Opening angle of about 30 ° has. This opening angle may be preferred range from 20 ° to 70 °. The angle to the axis 24 is then the Half of this opening angle.
- the key has a corresponding mating contact surface 38 of equal angle, it is indicated by dashed lines in Figure 1.
- the pins 32 are separate parts that are otherwise made in one piece Base part of the key are introduced. In the base part will be parallel to the axis 24 four holes for the pins introduced into this then the pins 32 held. The pins 32 jump slightly opposite to the Lower surface of the base part before. At their free end, the pins are dome-shaped educated. As a result, they reduce transverse to the direction of rotation standing attacks, but they form in both directions one sloping surface.
- Decisive is the inclined surface 50 in the direction of rotation of the release of the screw. It is clearly visible in particular from FIG. She rises like the helix of the threaded portion 42, thus causing an axial lifting in the sense of removing from the mounting part when using a corresponding counter-stop on the fastening part cooperates.
- This Counterstop is formed by the edge of keyholes 52, the complementary arranged to the pins in the drive portion 34 is provided are and make the returns.
- These key holes are in Formed edge area, thereby they take the pins 32 only partially. They cut through the contact surface 36, this leads to an approximately triangular lateral abutment surface 54, in both directions of rotation is available.
- the keyholes also go a bit into the material of the guide portion 22 in and form there annular support surfaces 56. At these beat the free ends of the pins 32, when a Torque from the key to be transferred to the fastening part. Due to the inclined surface 50 of each pin 32, it comes to the described axial lifting. This is due to the sloping Contact surface 36 and the associated mating contact surface 38 favors.
- the arrangement is chosen so that a nominal torque does not coincide with a Number of pins can be applied in the key, which is smaller than the intended number of pins 32. This avoids that in the Key all pins 32 except for one and thus a mat for has all fasteners.
- the contact surfaces 54 together with the support surfaces 56 form contact surfaces and are sized so that all pins 32 must be used for the transmission of nominal torque. If not all the pins 32 are present, the surfaces 54, 56 can not to absorb enough torque, rather it is due in particular the oblique surfaces 50 and also the cylindrical shape of the pins 32 for Take off.
- the inclined surfaces 50 only in the direction of rotation Be formed loosening, as in the embodiment of Figure 3 of the Case is. In the embodiment of Figure 1 and 2, they are also in the drive direction, So screwing, provided.
- the drive region 34 has an outer contour 58, the arcuate, after outside convex. This is the start of a special tool difficult in this area.
- the radius of curvature at the free end of the pins 32 is between 0.1 and 2 mm.
- the pins typically have a diameter of 4 mm. you are preferably cured, in particular in the region of its free end.
- the pencils are about 1.5 mm from the end surface of the base part before free.
- the guide part 20 of the key is now no longer a cylinder bore, but a centric pin that continues from the bottom of the base protrudes freely as the pins 32. Accordingly, the guide area 22 formed as a blind hole in the fastening part.
- the executed as a pen guide part 20 is in Base part of the key is not stored over the entire surface, but has the receiving bore a recess. This makes it possible, the pin-shaped guide member 20 by a sufficiently large force acting transversely to the axis 24, to press out of his position.
- a Predetermined breaking point in the pin-shaped guide member 20 may be provided. critical is that the leadership characteristics are lost if sufficient Transverse force acts. This sufficient lateral force is when using a normal key is not reached, but when using a key, not all pins 32 has.
- a cap 60 is indicated by dashed lines, the drive area 34 overlaps and is preferably designed so that the entire fastening part what a standard wheel nut looks like.
- This cap is anchored to the guide member 20, in particular offers the cross-sectional area 28 on.
- the guide portion 22 by a Recess 62 weakened. It is concentric with the axis 24 and extends axially over the entire length of the guide area 22. Sie can also be performed slightly shorter than the axial length of the guide portion 22 be.
- the guide region 22 has an inner wall 64. This runs at an angle alpha to the axis 24. The angle alpha is between 0 ° and 20 °, preferably between 0 and 10 °. Im shown Embodiment, it is about 1.5 °.
- the wall thickness between the inner surface 64 and the outer surface is chosen so that the guide area 22 can mechanically perform its managerial duties, but a torque the only attacks on the guide portion 22, rather for destruction This guide portion 22 leads, as to a release at a nominal torque.
- the wall thickness is in the range 0.3 to 1.5 mm. As the figure shows, the wall thickness varies over the axial length of the guide head 26. Preferably the wall thickness is lowest where the guide area 22 in FIG the drive region 34 passes. At this point can also be a small Be provided incision, for example, a groove be screwed, so that an effect as in Figure 2 is achieved, so the guide head 26 preferably shears off in the transition to the drive section 34.
- the drive region 34 is changed in FIG. Starting from one Key hole 52 and extends radially outward in the direction an edge region 66 with a positive slope and at an angle beta to a radial plane, which is shown in FIG. In other words closes radially outwardly seen on the contact surfaces 54 a rising Surface, in particular a conical surface, in the area of Keyhole 52 begins and increases outwards.
- This rising Surface additionally prevents that when using a universal key unscrewed with, for example, only one pin 32 of the fastening part can be. It causes a lifting force in the axial direction.
- the ramp surface rises at an angle between 5 ° and 30 °.
- the contact surface 54 is characterized in the direction of release smaller than in the direction of an attractive, screwing torque.
- the ramp surface 68 can also be used in the other embodiments be used, as at all the different embodiments arbitrarily combined with each other in terms of their individual features can be.
- the key in its embodiment according to Figure 8 corresponds essentially the key according to FIG. 3, but now the lower, free ends of the pins 32 rounded oval, the longer axis of the ellipse runs transverse to the axis 24.
- the contact surface reduced with the drive range.
- the fastening part according to FIG. 9 associated with the key according to FIG. 8 is similar to that of Fig. 3. It has an upward sloping inclined surface, also called edge region 66, on a cone sheath lies. In contrast to the embodiment according to FIG. 5, the course is now essentially straight and the pitch angle is beta chosen larger. For this border area 66, the following must be carried out: As the figures 2, 5 and 9 prove, the transition between the inclined edges of the contact surface 54 and the edge region 66th approximately on the axis of the keyholes 52 instead. In other words seen in the cross-sectional view there the deepest point of the contour.
- the pins 32 come especially in their curved edge area in contact and less with their in the direction of rotation front sections.
- the contact is perpendicular to the driving torque, while at increasing distance from the axis of the keyhole 52 the contact takes place increasingly at a larger angle.
- the key may be in the place of its lower corner (in the representation of Fig. 8, which is a profile view, seen) run beveled, so a Bevel 70, which preferably adapted to the ramp surface 68 is. It also runs rotationally symmetrical.
